About Wojciech

I am an experienced Java developer, software and solution architect with over 20 years of professional experience in developing scalable and secure systems – especially for customers from the DACH region.

I have a doctorate (Dr.-Ing.) in computer science and have implemented complex backend and full-stack solutions for the automotive, insurance, public administration and industrial sectors. My technological focuses are Java (Spring Boot), Microservices, Event-Driven Architectures, AWS Cloud, Kafka and Angular.

I enjoy working remotely, taking on both architecture tasks and implementation, and supporting teams with technical leadership, quality assurance and know-how transfer.

I look forward to new challenges in exciting projects – also part-time.
